Abstract :
We model the power fluctuation as cycle-to-cycle power gradient and minimize the mean of the power gradients using ILP. We propose scheduling schemes for three modes of datapath design: single supply voltage and single frequency (SVSF), multiple supply voltages and dynamic frequency clocking (MVDFC), and multiple supply voltages and multicycling (MVMC). Various experiments are conducted on selected high-level synthesis benchmarks. Experimental results in terms of several parameters, such as mean power gradient, mean cycle power, peak power, and power delay product, are presented.
